Dear Mr. Moseley:
Unusual Event Report UE-270/75-10, submitted on July 18, 1975, described a f ailure of the emergency condenser discharge valve CCW-8 during test.
The apparent cause of the incident was determined to be moisture in the limit switch junction box.
It was stated that ap-propriate action would be taken to prevent moisture buildup in the limit switch compartment of valve CCW-8 by October 1, 1975. Materials were ordered for a modification to place a vent and electric heater in the motor and gear limit switch compartment of valve CCW-8; however, delivery time of t1ese parts has precluded instc11ation by October 1, 1975.
It is expected that this modification will be completed by November 1, 1975.
Veryltruly yours,
